"(1) This section applies where a court— (a) proposes to impose a custodial sentence for a sexual or violent offence committed on or after30th September 1998 ; and (b) considers that the period (if any) for which the offender would, apart from this section, be subject to a licence would not be adequate for the purpose of preventing the commission by him of further offences and securing his rehabilitation. (2) Subject to subsections (3) to (5) below, the court may pass on the offender an extended sentence, that is to say, a custodial sentence the term of which is equal to the aggregate of— (a) the term of the custodial sentence that the court would have imposed if it had passed a custodial sentence otherwise than under this section (‘the custodial term’); and (b) a further period (‘the extension period’) for which the offender is to be subject to a licence and which is of such length as the court considers necessary for the purpose mentioned in subsection (1) above. ... (5) The term of an extended sentence passed in respect of an offence shall not exceed the maximum term permitted for that offence."
"Subsection (2) of section 80 above (length of discretionary custodial sentences) shall apply as if the term of an extended sentence did not include the extension period."
"(1) This section applies to a prisoner serving an extended sentence within the meaning ofsection 85 of the Powers of Criminal Courts (Sentencing) Act 2000 . (2) Subject to the provisions of this section and section 51(2D) below, this Part, except section 40A, shall have effect as if the term of the extended sentence did not include the extension period."
"Subsections (2B) and (2C) above shall have effect as if the term of an extended sentence (within the meaning ofsection 85 of the Powers of Criminal Courts (Sentencing) Act 2000 ) included the extension period (within the meaning of that section)."
"6. It is to be noted that although the word 'custodial' is used in relation to sub-paragraph (b) quoted above, this does not necessarily imply a period of imprisonment. It merely denotes a period during which any offender is liable to be imprisoned if he is discovered to be in breach of the licence. 7. That must be compared withsection 1 of the Sex Offenders Act 1997 , which sets out in tabular form the applicable period for which any person convicted of a sexual offence is required to register and to notify the appropriate authorities. In relation to the sentence of imprisonment which is passed, the appropriate wording of the table is: 'A person who, in respect of the offence, is or has been sentenced to imprisonment for a term or more than six months, but less than 30 months.' 8. We note the difference between the phrase 'custodial sentence' and the phrase 'a term of imprisonment'. It seems to us that, on the plain construction of the latter Act, 'a term of imprisonment' connotes actual and immediate imprisonment and does not include a sentence of extended licence during which he is liable to be imprisoned but will not necessarily be so. 9. Accordingly, we take the view that the requirement of registering for an indefinite period was incorrectly imposed and that the correct period should be 10 years, beginning with the relevant date in accordance with the section ..."
"14. By reason of the definition of 'custodial sentence' under section 76, section 85(1) must therefore read: 'This section applies where a court proposes to impose a sentence of imprisonment or detention.' Section 85(2) must read: '... the court may pass on the offender an extended sentence, that is to say a term of imprisonment of detention which is equal to aggregate of--- (a) the term of imprisonment or detention that the court would have imposed... (b) a further period ... for which the offender is to be subject to a licence.' Thus read, it is clear that the term of imprisonment or detention includes the extension period and is not confined to the custodial term. That reading is mandated by the definition of custodial sentence in section 76. 15. It is also consistent with the nature of a modern determinate sentence of imprisonment or detention. It is not, as the phrase might in ordinary language suggest, an order for a period of incarceration of defined length: it is an order for a period of restriction on freedom of the offender, which begins with a period of incarceration and then may include a period of release on licence and will end with a period during which the offender is liable to be ordered to serve the unexpired term if he reoffends during the currency of the term. All that an extended sentence does is adjust the length of the second (licence) period. Therefore, for the purposes of section 28, the whole length of the extended sentence is to be taken into account in determining the length of the qualifying sentence. The qualifying sentence here was 2 years."
"... no great weight is to be attached in the present case to the fact that section 85(2) refers to the aggregate of the custodial term and the extension period as ‘a custodial sentence’. More attention needs to be focused on what actually happens in reality when such a sentence is passed."
"In short, when an offender is detained during the extension period of a section 85 sentence, such detention must be subject to review by a judicial body. No court has ordered his detention during that period: prima facie the sentencing court took the view that he could be dealt with in the community during that period ... In cases of extended sentences under section 85, it is the executive which decides upon an offender's recall during the extension period, and because that detention has not been ordered by a court it must be supervised by a judicial body."
